"V_Arc-ISO" is the signal relating to the arc voltage at the power source output ("electrode-workpiece" voltage), sup-
plied in insulated and reduced mode.
The "V_Arc-ISO" signal is available with the following full-scale values:
• voltage from 0 to 5V, corresponding to arc voltage from 0 to 250V (reduction ratio = 1/50);
• voltage from 0 to 10V, corresponding to arc voltage from 0 to 250V (reduction ratio = 1/25);
The full-scale value depends on the position of the Dip 2 dipswitches on the interface board (see fig. 3.6).
The machine is supplied with the reduced arc voltage output insulated at 1/50 Varc.
